This node informs gzvm driver to start probing if geniezone hypervisor is available and able to do virtual machine operations. [Detail] The debate of using dt or not remains intact, and gentle ping seems not working on this issue. We'll keep this patch for further discussion and move forward in order to rebase based on the latest rc release.
